tps4100 Tripath Technology Inc., tps4100 Datasheet - Page 3

• Manufacturer Part Number: tps4100
• Description: Four Channel Bridged Output Power Stage
• Manufacturer: Tripath Technology Inc.

Electrical Characteristics
T
Note 6: Minimum and maximum limits are guaranteed but may not be 100% tested.
Performance Characteristics
T
shown are applicable only when the TPS4100 is used in conjunction with the TCD6001 Class-T
Controller. See Application/Test Circuit of TCD6001 data sheet for additional information.
AM Mode
T
Bandwidth = 20kHz. See Application/Test Circuit.
.
Note 7: The TPS4100 heat sinking in AM Mode must be increased (as compared to Class-T mode) to sustain the
typical output numbers. This is due to the lower efficiency of Class B output stage operation.
